Unix command-Line CSV viewer

sc is a command-line spreadsheet program that's been around a long time, likely available in your package manager. Here's a Linux Journal intro article to it:

There's a tool, CSVfix, which helps with viewing CSV files.

CSVfix is a command-line stream editor specifically designed to deal with CSV data. With it you can, among other things:

• Convert fixed format, multi-line and DSV files to CSV
• Reorder, remove, split and merge fields
• Convert case, trim leading & trailing spaces
• Search for specific content using regular expressions
• Filter out duplicate data or data on exclusion lists
• Perform sed/perl style editing
• Enrich with data from other sources
• Add sequence numbers and file source information
• Split large CSV files into smaller files based on field contents
• Perform arithmetic calculations on individual fields
• Validate CSV data against a collection of validation rules
• Convert between CSV and fixed format, XML, SQL and DSV
• Summarise CSV data, calculating averages, modes, frequencies etc.

A simple way to view CSV files on the command-line is to pipe the .csv file into the column utility with the column delimiter set as a comma:

column -s, -t yourfile.csv

It seems like this question overlaps (at least partially) with my similar question on StackOverflow:

Command line CSV viewer?

The top answer there is currently:

column -s, -t < somefile.csv | less -#2 -N -S
